Obturating Rings or Gas Check Bands
Located at the widest section of a munition’s body, these features are designed to trap gas when the projectile is fired, thus improving the forward propulsion of the munition out of the barrel.
OSMP451
Analyst Note:
Although this munition started out life as a mortar projectile of the M492-pattern, it has been modified to be dropped from an unmanned aerial vehicle (UAV) and, in its present state, could not be fired from a conventional mortar. As such, it is correctly classified here as an air-delivered bomb. (ARES)
OSMP260
Analyst Note:
As a result of the rapid introduction of new models and variants during ongoing conflicts, sometimes a munition is issued with a provisional designation, or with no designation at all. In other cases, the designation is not yet known to researchers. (ARES)

2 Analyst Notes:
The plum-coloured plastic ring at the nose of this mortar projectile (placed over its fuze) and the black plastic propellant cover (placed over its tail) are both fitted for transport and storage, before the projectile is loaded into a cardboard tube, and then packed into an outer crate. The propellant cover obscures the perforated cylindrical tail assembly in this image. (ARES)
OSMP208
Analyst Note:
The OF-NMR is a rocket-assisted mortar projectile, which uses a solid-fuel rocket motor located in the cylindrical portion of the body, below the ogive, to extend its range. Rocket-assisted mortar projectiles are rarely encountered. (ARES)
OSMP216
Analyst Note:
The “+” marking is a weight classification symbol which indicates standard deviation. One “+” sign indicates a deviation from 0.33% to 1.00% of the stated weight. (ARES)
OSMP169
Analyst Note:
The 120 mm 3-Z-2 incendiary mortar projectile contains 6 incendiary elements, four large and two small. These are hollow steel ‘cups’ filled with an incendiary mixture of an unknown type, but understood to be comparable in effect to thermite. (ARES)
